INSTALLATION TROUBLE SHOOTING

Use only flexible tubing for inlet and outlet porting to hy- draulic source to prevent wear of components.

Be sure return lines are sized larger than supply lines and similarly pressure rated.

Inspect the system hoses frequently for wear or damage and, if necessary, replace them immediately. Never plug hose leaks with your finger, tape or any similar devices.

yDo not use PTFE tape on the inlet and outlet port fittings. Loctite® 571 pipe thread sealant or equiva- lent is the recommended sealant.

yTighten the inlet and outlet fittings to 50 - 70 ft lbs (67.8 - 94.9 Nm).

SERVICE

NOTE: The 67314-B hydraulic motor will contain about one pint of hydraulic fluid. Drain this fluid before attempting any disassembly.

NOTE: Do not disassemble this motor except in a clean area. Any dust or dirt contamination of this assembly will shorten the service life of this motor and other system components.

NOTE: All power supply pumps should have a ten micron filter on the return line and a 100 mesh filter on the inlet. Fail- ure to maintain filters will shorten service life of this motor and other system components.

If the pump will not cycle or will not deliver material.

yBe certain to check for non-pump problems, including kinked, restrictive or plugged inlet / outlet hose or dis- pensing device. Depressurize the pump system and clean out any obstructions in the inlet / outlet material lines.

yCheck all seals, including track gaskets.

yCheck direction of “U” cup lips.

Motor is running beyond recommended temperature op- erating conditions.

yHydraulic oil cooling system is not working.

yPiston seals are worn, replace seals.

Leakage from weep hole in retainer.

yDetection of rod seal wear, when the amount this ex- ceeds is 5 cc / day, replace wiper and rod seal.

yPreventive maintenance issue, consult the factory for rec- ommendations.

Motor stalls at fully retracted or extended position.

yInsufficient pressure to motor (65 p.s.i. / 4.5 bar mini- mum).

ySprings need to be replaced.

yValve is damaged, service hydraulic motor.
